Answer:2
Step-by-step explanation:
Answer:the value where the line crosses the y axis
Step-by-step explanation:
its crossing through the y-axis not the x-axis because. The y-intercept is where the line crosses the y-axis. for example, you see the line cuts across the y-axis at -2. This makes our y-intercept -2.
Answer:
y=3/2x + 1
Step-by-step explanation:
yeah-ya..... right?
By splitting the shape into a semi-circle and rectangle, we can see that we have a semi-circle with a diameter of 14 cm and a rectangle with dimensions of 28 cm by 15 cm. To find the area of the entire shape, we can add the areas of the two shapes up.
We can find the area of the semi-circle using the formula 
, where 
is the radius of the semi-circle. In this case, the area would be:
The formula for the area of a rectangle is 
, where 
is the length of the rectangle and 
is the width. In this case, the area would be:
Thus, the area of the total shape is:
So basically, the first question after the word problem is asking you to write an equation to represent the value of Mama's car after a certain amount of years (t). Since the value of her car decreases by 3% each year, you could multiply 3% by the original value of her car, to find what 3% is, OR you could subtract 19,400 (the value of her car after 1 year) from 20,000 INSTEAD of multiplying 20,000 by 3%.
Equation: value=20,000 - 600t
To answer the next question, just plug it into the equation you created.
500<20,000 - 600t
-19500< -600t
32.5>t
Final Answer: It would take at least 32 and 1/2 years for the value of Mama's car to be less than $500.
Hope this helps!! :)
